Roller Blind Cog

Roller Blind Cog

thingiverse

This is a cog I made for a Roller Blind. I needed a shorter pull string to allow for automation with an Alexa smart Motor. The shorter string had ball distances that were slightly too close to go around the old cog. Who knows, this might be just the thing someone is looking for ... so I thought I would share. The Blender 3d file is in there too in case you wanted to slightly modify it.
